Playback Questions (780G & VMR9)

[pBS]

All I want is smooth 1080i video with no tearing, is that so much to ask?

try ffdshow latest beta6 tryout w/nv12 colorspace output only and set interlace media type on output tab without main deinterlacing tab checked...
no ha but smooth...and not bad on cpu..

other wise it sounds like a tweak might fix you...play with the ha settings in dxvachecker..
be sure to check the show all box and notice things that mention hd mpeg2...
[i forget which one works for lower end cards]
try loading this into dxvachecker in video acceleration settings...
[save as xxxx.vas]

I'd have to agree with the previous posts. I have a 780G system and I am getting good 1080i playback on XP with the following:

Microsoft DVR-MS mux for recording
ATI driver 8.11
ffdshow w/ hardware interlacing enabled in output section
VMR9 Full screen exclusive
HDMI output to TV at 720p

If I try a different driver, decoder or renderer, I get slight stuttering on 1080i due to the interlacing. This does not give me full hardware accelerated decoding, but, that is not necessary for good playback. Hardware accelerated deinterlacing is the key for good 1080i ATSC playback.

[pBS]

yea, what he said...
to add, the lower end cards gpu 'decode' isn't quite up to snuff, and ffdshow is very error resilient, while still offering the bulk of hardware accelerated assistance...
it even plays h.264 decent now..
[best of both worlds, halfway between core-avc and pure hardware decode]
problems with hardware decode require a driver update to fix, while ffdshow can roll with the punches better..

[Squid]

Could somebody link the ffdshow they are talking about, I keep finding much older versions.

[pBS]

first link in google searching for ffdshow tryouts...
http://downloads.sourceforge.net/ffdshow...081219.exe
these are new folks that are continuing the originators work..

i sure am glad someone picked up the reigns on this one, i'd die if they stopped development!
becoming quite usefull for things other than mp4/divx....

[pBS]

just tried the new deinterlacer [Yadif] and it looks great! of course with the downside of all the extra cpu usage...[about 50-60%] but nice n smooth..
PQuality is nearly identical...
check yv12 colorspace only to use ffdshow deinterlacers..
[it is most efficient colorspace and you'll need the help]
and uncheck 'set interlace flag in output'

i did get a audio out of sync after comm. skip tho....

I'm having a slightly different problem with my 780G in VMR9 Exclusive (The only mode that gives me good picture quality). I just recently re-imaged Vista HP and I also just added a new TV with a HDMI connection instead of an old d-sub monitor. I installed Catalyst driver 9.1

I have problems that often when the computer comes out of stand-by the HDMI monitor detects no signal. Sometimes I think order counts. If I turn the monitor on first then the computer does better, but not always. If I then toggle the computer to stand-by and back on again, I get a signal. Sometimes however, the ATI driver has gone back into a default screen resolution instead of 1920 x 1080.

I also have problems that sometimes when I exit PVR2 the 780G also stops sending a signal. Toggling to stand-by and back again fixes it. I assume that is just restarting the video process.

I have seen some discussion of this elsewhere. Some suggested to set the power options to never turn off the monitor also to turn off the ATI External Events service. I got mixed results doing these things. I sometimes see a Vista message saying some monitor process stopped and has been restarted automatically.

Anybody else having these issues? Are folks having better luck with different version of the ATI drivers?
